@riverI'm not about to switch away from signal, it's still one of the most privacy focused apps out there. And from a privacy vs UX perspective probably still the best app on the market.

Anyway, usual recommendations for signal alternatives: Conversations (XMPP), Wire, Briar (uses Tor, no desktop version), and if you don't care about being open source/free software there is also Threema.

A lot of those alternative's usability depends on your needs and expectations.
